hi, ZhiTao
the following is abstracted from the Library overview of Wt doc, try them,
I have never used it:-)
When the requirements for stateless slot learning cannot be met you will
have to resort to writing JavaScript manually. Wt provides a number of
mechanisms to integrate JavaScript code with C++:
- Using
JSlot<file:///home/cx/software/wt-2.99.1/doc/reference/html/classWt_1_1JSlot.html>,
you can specify the JavaScript for a slot, when connected to an
EventSignal<file:///home/cx/software/wt-2.99.1/doc/reference/html/classWt_1_1EventSignal.html>.
- Using
JSignal<file:///home/cx/software/wt-2.99.1/doc/reference/html/classWt_1_1JSignal.html>,
you can emit a C++ signal from JavaScript code, using a JavaScript function
Wt.emit().
- Using
WApplication::doJavaScript()<file:///home/cx/software/wt-2.99.1/doc/reference/html/classWt_1_1WApplication.html#2a92457b9212cef4057cb54e56183967>,
you can call JavaScript code directly as part of event handling.
